Stainless steel construction including 70 microns mesh makes the filter strong and durable.                                                                                             

Low instalaton height (4 inches) from the pond water level to the top of the filter allows it has very low ceiling clearance.                                                     

Open design, large sloping, straight and big port waste tray makes it easy for waste to be pushed out, easy access to remove leaves and large debris.

Filter mesh support bars are also designed to easily lift up leaves, string algae and large debris up to the waste tray.                                                     

The silicone sealing mechanism is UV-resistant, simple, and provides an excellent seal.                                                                                                               

Transparent filter lid makes its easy to observe the operation, with access for maintenance while reducing operating noise.                                        

Can operate in fully automatic mode (AUTOMATIC) or custom timer mode (MANUAL), equipped with counter of cleaning cycles.

Optimally designed to assure maximum submersed drum’s surface area for maximum flow in a smallest possible installation space.

Open design chambers for input/output water for easily observing the water level, degree of dirtiness or any debris and leaves.

Designed with maximum number of outlets and inlets that allow instlation in gravity fed system has stable and higher flow rate.

Special stainless steel water-efficient spray nozzles provide high water pressure and high water penetration to help keep the mesh clean.

Equipped with bypass ports which can be manually opened to bypass the mesh drum to allow water to continue flowing in case of repair.

Control box features simple ‘plug & play’ design that makes it easy to use, stable and durable, with easy maintenance.

Low water warning and automatic power disconnect to the circuit pump when hooked up as described in user guide.                                               

ABOUT US

Rotary Drum Filter (RDF) is an automated filtration system for Koi ponds. It acts as an excellent mechanical filtration to automatically remove the debris and fish waste out of the water column quickly and regularly through a standard 70 micrometer fine mesh with automated washing cycles to reduce contaminants and maintain crystal clear water.

With FREE-Drum-Filter, you no longer need to perform painstaking tasks such as cleaning filter media pads or cleaning settling chamber, backwashing mechanical filters or changing the water periodically. FREE-Drum-Filter will take care all of those tasks automatically. It quickly remove waste from water column that help reduce toxins from the pond and help your fish grow optimally and keep your pond water crystal clear. 

Our RDF is designed by engineers that are also pond-enthusiasts and longtime koi keepers who understand what it takes to effectively maintain koi ponds. After many years of research and testing in many different koi pond environments, we have come up with the products that assure the highest level of functionality that are still simple and easy use and be maintained by the pond hobbyist with no engineering background.
